21:26 CoCoALib Feature #379: Iter for subsets/tuples
I have now added a new ctor *@SubsetIter(n,k)@* which iterates over all subsets of cardinality @k@.
Still do not ...

20:42 CoCoALib Feature #379 (In Progress): Iter for subsets/tuples
I did this some time ago: it is in *@combinatorics.H@*.
I think there should be a version which iterates only over s...

20:43 CoCoALib Design #305: FreeModule: unique copy?
*ANNA* What is the status of this?
Feasible to complete before 0.99850?

14:02 CoCoALib Bug #1773 (Resolved): CyclotomicFactorIndexes: gave wrong answer
I think I have fixed it now. I'd better add a test.

I got a wrong answer from @CyclotomicFactorIndexes@; it missed the index 6... John Abbott
13:43 CoCoALib Feature #1770 (Resolved): Evaluate polynomial function/class
I have separated the evaluation code from the cyclotomic code, and put it in a new file.
Must still document the new...

21:30 CoCoALib Design #1768: Limit indentation in verbose mesgs?
*Anna* will test the updated code shortly (I hope)
John Abbott
21:29 CoCoALib Slug #1769 (Feedback): FixedDivisor is sometimes surprisingly slow
I regard this as fixed: the remaining work is in issue #1770 John Abbott
21:16 CoCoALib Design #1771 (Resolved): Hadamard bound: field names
During a telephone discussion with Anna, we decided it makes sense to change the field names. Of course, this is not... John Abbott

21:34 CoCoA-5 Support #1636 (In Progress): Missing/Incomplete manual entries
Here is a start to finding which functions need manual entries but don't have them.
Below is some CoCoA-5 code whi...

22:29 CoCoA-5 Feature #980 (In Progress): CoeffSize: function to measure the size of coeffs in a poly
JAA notes that @FloorLog2@ is faster than @FloorLog10@ -- a quick check suggest at least 100 times faster.
Also @Flo...

22:17 CoCoA-5 Design #1772: Continued fraction: arg type RAT or RAT/INT?
Possible options:
* disable the auto conversion from @RAT@ to @INT@ -- JAA doubts that this is wise (it could cause ...

22:12 CoCoA-5 Design #1772 (New): Continued fraction: arg type RAT or RAT/INT?
Currently the continued fraction functions expect an arg of type @RAT@.
This cause a problem in one program I wrote ...

19:41 CoCoALib Slug #1769 (Resolved): FixedDivisor is sometimes surprisingly slow
I have changed the code to use the new prototype evaluation code (see issue #1770), and it is now usefully faster :-)... John Abbott

12:12 CoCoALib Design #1771 (Closed): Hadamard bound: field names
CoCoALib and CoCoA-5 offer a function to compute Hadamard's bound (for determinants).
The function actually compute ...

I made a quick prototype, and used it in a revised version of @FixedDivisor@ (in @PolyRing.C@).
It made the code abo...

23:15 CoCoALib Feature #1770 (Closed): Evaluate polynomial function/class
Create a class(?) to make it easier to evaluate polynomials.
A first prototype is in *@SparsePolyOps-cyclotomic@* (...

10:05 CoCoALib Design #1768 (In Progress): Limit indentation in verbose mesgs?
The point is whether we should impose a limit. I agree that 20 is probably too low. We can try with 100, and possib... John Abbott
